74LCX574
Low Voltage Octal D-Type Flip-Flop
with 5V Tolerant Inputs and Outputs
Features
■ 5V tolerant inputs and outputs
■ 2.3V–3.6V V_CC specifications provided
■ 7.5ns t_PD max. (V_CC = 3.3V), 10µA I_CC max.
■ Power down high impedance inputs and outputs
■ Supports live insertion/withdrawal⁽¹⁾
■ ±24mA output drive (V_CC = 3.0V)
■ Implements proprietary noise/EMI reduction circuitry
■ Latch-up performance exceeds JEDEC 78 conditions
■ ESD performance
– Human body model > 2000V
– Machine model > 200V
Note:
1. To ensure the high impedance state during power up
or down, OE should be tied to V_CC through a pull-up
resistor: the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
General Description
The LCX574 is a high-speed, low power octal flip-flop
with a buffered common Clock (CP) and a buffered
common Output Enable (OE). The information presented
to the D inputs is stored in the flip-flops on the LOW-to-
HIGH Clock (CP) transition.
The LCX574 is functionally identical to the LCX374
except for the pinouts.
The LCX574 is designed for low voltage applications
with capability of interfacing to a 5V signal environment.
The LCX574 is fabricated with an advanced CMOS
technology to achieve high speed operation while main-
taining CMOS low power dissipation.
